blueberries

In a prior article about the best foods for fit eyes, I strongly recommended blueberries, grapes and raisins. I said, "According to Dr. Abel, [blueberries, grapes and raisins] contain anthocyanins, which improve night vision. A cup full of blueberries, huckleberry jam, or a 100 mg bilberry supplement should improve dark adaptation within 30 minutes."
